Starring: Judd Hirsch, David Krumholtz, Rob Morrow, Alimi Ballard
Visible crew/equipment: When Don and David chase down Jose Salazar and get him down on the ground to cuff him, a crewmember (presumably the second cameraman shooting Jose's low angle closeups) is lying on his back behind David.
Continuity mistake: When Jose Salazar is eventually arrested, he is knocked to the ground, and handcuffed behind his back. However, the next shot shows Jose pushing himself up with his own hands. His hands are then behind his back in the following shot.
Amita Ramanujan: Charlie, where did you learn all this stuff about assassination?
Charlie Eppes: If I told you that I'd have to kill you.
Amita Ramanujan: Okay, seriously.
Charlie Eppes: Seriously.
Trivia: The episode revolves around a man killing people with the same first names as the thirteen apostles (Mary Magdalene being the 13th), and killing them in a similar fashion in which the apostles died. At one point, Colby and David find a box with a mannequin's head in it. This is a reference to the film Se7en, in which seven people are killed for committing one of the seven deadly sins. The film ends with the main characters finding an actual head in a box.
Question: This question is about the mistake where a SWAT officer has a magazine backwards in his MP5. I know this would be impossible on a real weapon. But, how could it have happened in filming? Rubber cast weapon? Very badly worn prop weapon? Set armourer with a hammer and no clue?
